Clients implementing this editor input interface should override
Object.equals(Object) to answer true for two inputs
that are the same. The IWorbenchPage.openEditor APIs
are dependent on this to find an editor with the same input.

File-oriented editors should support this as a valid input type, and allow
full read-write editing of its content.

A default implementation of this interface is provided by
org.eclipse.ui.part.FileEditorInput.

All editor inputs must implement the IAdaptable interface;
extensions are managed by the platform's adapter manager.

Method Detail

getFile

The IFile returned can be a handle to a resource
that does not exist in the workspace. As such, an editor should
provide appropriate feedback to the user instead of simply failing
during input validation. For example, a text editor could open
in read-only mode with a message in the text area to inform the
user that the file does not exist.
